The preferred audio language setting has nothing to do with the sequence
or number of APIDs in the channel definition. The APIDs are always stored
in the same sequence as they are broadcast.

What I was referring to was a possible change in the way VDR sets the APIDs
when switching to a channel.

As I sais, I'll need to think about this a little more...
